After the Sony updater is finished you will get a BSOD, all you have to do is press O button.
I think it´s helpful for some people to back-up the wifi setting with
net configure manager 1st.
Also the use of the new pspident can be helpful.
(note: new pspident may display your psp as a fat)

I up&downgraded yesterday from 6.20 to 6.35 and back to 6.20 and i lost my custom gameboot and custom sense-me icon^^

If people have a look to http://img705.imageshack.us/img705/7831 ... rview0.png
they probably think they can downgrade a go or some 3000 without any issue deeper as 6.20
Nan dump?! Sleepfix semibrick^^

This is because PSPident only shows the lowest OFW your mobo supports where a HEN could be used (explaining why you see 5.03)
The last column in the chart lists the lowest possible OFW the mobo supports, not the lowest OFW it can actually downgrade to, nor the lowest OFW where a HEN is available.
